The WaterBoiler was passed on to the Antwerp based design studio Unfold. Unfold has made an adaptation: a salvaged, PET bottle was replaced by a cut glass bottle which holds a 3D printed ceramic water filter. Activated carbon can be filled in the ceramic water filter and act as a purification device. Besides, adaptor piece was designed by Fabio Lorefice and then got 3D printed. The water filter is still a prototype, it is part of a research project on the reuse of various parts and components and potential benefits of ceramic 3D printing in the developing world.
